Application filed March 4, 1918. Serial No. 220,213.

To all whom it may concern:

'Be it known that I, JAMES M. RUDE, a citizen of the United States, residing at Covington, in the county of 'Kenton and State of Kentucky, have invented certain new? and :useful "Improvements in Can- Treating Apparatus; and I do hereby declare the following to be a fullfclear, and exact description of the invention, such .as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in mechanism for the -treating of used cans for adapting them for re-use, and has as its primary objectthe provision of means for cutting away a section of the head of a can to enable the canto be severed intermediate'its ends.

"With this :and further objects in view as will in part hereinafter become apparent and in part 'be stated, the invention comprises certain novel constructions, combinations and arrangements of parts as subsequently specified and claimed.

In the accompanying drawings,

Figure 1 is a view partly in elevation and partly in vertical section of an appa ratus embodyingthe features of the present invention.

Figs. 2, 3' and 4 are vertical sections taken, respectively, on the planes indicated byflines 22, 3-3, and H of F 1.

Fig. 5 is a horizontal section taken on the plane indicated by 1ine-5'5 of Fig. 1,

and looking downwardly.

Referring to the drawings by numerals,

1 indicates an appropriate standard or frame in which is s'lidingly mounted across head *2 .to which is .swiveled a supporting downwardlyextending threaded shaft '3. A worm gear 1 is appropriately housed in the frame 1 and threaded onto the shaft 3 in position for causing theshaft tomove longitudinally when the worm gears revolve. Aworm shaft 5 is journaled in the frame 1 and provided with a thumb head or other operating connection 6, the shaft beingformed with a worm '7 meshing with the gear 4, :so that the'said gear may be revolved for shifting the cross head *2 up or down as may be found desirable. The ;cross head .2 is formed with a transverse aperture 8 for receiving a bar 9 and the bar and aperture are preferably polysided so as to prevent the bar from revolving. Bosses 10, 1O outstand from the cross head for increasing the bearing support for the bar 9, the said bosses being formedwith bores continuous of the aperture8. A set screw '11 penetrates one of'the bosses .10 and engages the bar 9' for retaining the same against moving logitudinally but allowing the bar to be adjusted longitudinally by loosening and re-setting the set screw. The bar 9 is provided with graduations 12 indicating the extent of adjustment according to the length of the can to be treated.

The outer end portion of bar 9, that is the end more remote from frame '1, is engaged by a sleeve 13 locked in place by a set screw 1%. Upstanding from the sleeve 13 is a plate 15 which is a'djustably engaged by a plate 16, the latter being formed with a slot 17 and a pin or bolt 18 engages the plate 15 and extends through the slot 17, the bolt being engaged by a nut for looking the plates 16 and 17 at; any desired point of adjustment. The extreme upper end portion of plate lGis formed with a notch 19 proportioned and located for snugly receiving the longitudinal internal bead 20 of the can 21 which is to be operated upon. The bead .20 is the usual lock seam of an ordinary can. a

The forward portion of the can 21 is supported on framework carried by the bar 9. The said framework may assume various forms, and preferably consists of a pair of sleeves 22, 22, from which upstand bars 23*bifu-rcated to form arms 24, One arm of each bar 23 is connected with the coresponding arm of the other bar 23 by a yokeshaped bar 25, and the other two arms are correspondingly connected, each of the yoke-shaped bars 25 being adjustably mounted in sockets in the respective arms 24 and locked therein by set screws 26. A set screw 27 is passed through one of the sleeves 21 and engages the bar 9 to hold the .iramework against longitudinal shifting. The yokes 25 are located to sustain the can in proper position for being operated upon and are adjusted by manipulation of set screws 26 according to the size of can to be treated. This adjustment is proportioned to the adjustment of the shaft 3 and it should be'noted that these adjustments may be made within certain limitation and when cans of a greater variation than those provided for are to be treated, the bar 9 is withdrawn and turned over to the position indicated in dotted lines in Fig. 1. The bar 9 is formed with an offset bend 9 which thus provides for accommodating a different series of sizes of cans when in one position than when in another position. When the bar 9 is turned over as indicated in dotted lines, I provide a new set of yokes 25 and a new plate 16 proportioned to enable taking advantage of the new range of adjustments.

Journaled in the upper portion of the frame 1 is a shaft 27 driven by a pulley 28 and belt 29 or other appropriate driving mechanism not shown. An emery wheel or other abrader 30 is fixed to the end of the shaft 2'7 and has its upper portion extending between the yokes 25 so that a can passed over the plate 16 and along the yokes 25 will be caused to surround the wheel 30. An operating lever 31 is pivoted at 32 to the frame 1, the pivot being preferably mounted in a pair of ears upstanding from the frame. Lever 31 is provided with a short elbow 33 projecting below the upper portion of the frame 1 for limiting the possible extent of upward movement of the free end of lever 31. A spring 3% is interposed between the lever 31 and the upper portion of frame 1, so as to sustain the free end of lever 31 in a raised position and a set screw 35 is passed through a portion of lever 31 in position for engaging the frame 1 to limit the downward movement of the free end portion of lever 31. A projection 36 extends downwardly from lever 31 in position to strike the can 21 along the line of its bead 2O immediately above the wheel 30. The projection 36 extends along the lever 31 a distance equal to the width of the wheel 30 so that when the lever 31 is pressed down toward the can the projection 36 will engage the can and spring the walls thereof sufiiciently to cause the bead 20 to be depressed against the cutting surface of the wheel 30. This pressure is maintained until the wheel has cut away all of the bead and left only one thickis manually slid off from its engagement with the yokes 25 and the plate 16. It is to be observed that the engagement of the bead 20 with the aperture 19 prevents revolving of the can during the grinding operation.

After the bead has been cut away as described, the can may be severed somewhere in the planes of the cut away portion, whereby a shorter can is produced or where the can is of suflicient length two short cans may be produced. This operation is particularly desirable where some injury has occurred near the opened cover of the can and a section of the can can be removed to leave only the good part of the can for future use.

What I claim is 1. In can treating apparatus, the combination with an abrader, of adjustable can sustaining means adjacent thereto, and means for pressing the bead of a can mounted on said sustaining means laterally against the abrader.

2. In can treating apparatus,the combination with an abrader, of a lever movable toward and away from the abrader and adapt ed to engage and press the longitudinal head of a can laterally toward the abrader,

and means for limiting the movement of the lever.

3. In can treating apparatus,the combination with an abrader, of a lever movable toward and away from the abrader and adapted to engage and press the longitudinal bead of a can laterally toward the abrader, and means for limiting the movement of the lever toward the abrader for limiting the extent of action of the abrader on the bead and preventing cutting of the bead after the abrader has removed all but one thickness of the wall ofthe can at the bead.

a. In can treating apparatus,the combination with an abrader, of a can support adjustable relative thereto, a worm gear for adjusting the support, and means for pressing a portion of the can sustained by the support laterally toward the abrader.

5. In can treating apparatus, the combination with an abrader, of a can sustaining framework, an adjustable cross head carrying the same and adapted to be shifted for moving the framework relative to the abrader, a worm gear for shifting the cross head, and means for pressing a portion of a can sustained by the framework toward the abrader.
